spoken like a true skeptic! Only the finding of treasure is the proof! You just lack the imagination to find any!
To be fair, I'd be happy with even one or two pieces of solid, documented evidence that can be directly observed today. Not something that some guy heard, not a "fact" that "everyone knows," and not a telltale artifact that no one can locate today, but an actual, tangible piece of evidence that cannot be reasonably questioned. I do not need the treasure as proof, but I would like to see some proof of a treasure. The further that I dug into this pile of manure, the more I found that the "fact" that "everyone knows" was simply a corrupted repackaging of an earlier horse apple, and that every piece of physical evidence that existing theories hinge upon can't be located today, has no hard documentation, and generally appeared when a recovery operation was about to go bankrupt and investors were being solicited. If there is no physical evidence of something (it can't be found, no photograph, we don't have a chain of custody, etc.), then for all intents and purposes it doesn't exist. It's a story. There are a lot of stories associated with this legend, and I don't believe that I've ever seen so many people take stories as factual without any tangible proof outside of a church before. I'll give God the benefit of the doubt but this...this boggles my mind.
What I lack in imagination, I make up for in logic. This makes me unpopular with some people. Sucks to be them, I suppose.

As I've said in the past, a person with a strong theory based on strong evidence has nothing to fear from a skeptic. A person with a crap theory based on crap evidence has much to fear from a skeptic. I'd go further to say that the theorist with facts to back up their talk looks forward to someone saying, "Prove it," as that's exactly what they want to do. The theorist without the facts, or the wrong facts, or the facts that aren't really facts does not welcome this sort of discussion and often becomes offended. If this request offends someone...well, why? Why would someone who wanted to prove something ever be bothered by someone asking them to do just that?
Also, a side note...how does a lack of imagination prevent someone from finding treasure? Most stories about found treasure that I'm familiar with involved chance/luck, laborious and thorough research, or both. I'm not familiar with anyone ever finding a treasure simply because they wished it to be there. I won't presume to speak for every treasure hunter (professional or otherwise) in the world, but I feel safe in stating that if the story has a high percentage of being real and the research confirms it, they not only have a good idea of where to look, but also what they're going to find when they get there.
If something is or was buried in the Money Pit, what is/was it? Think about this question and how it applies to what I just typed.
